Abstract: The present invention relates to furanoid sugar amino acids and their salts which carrying an additional chiral center at C6-position with substituents and resembling the side-chains of natural amino acids. More particularly, 6-substituted-6-deoxy-6-amino-2,5-anhydroaldonic acids and their 3,4-dideoxy congeners, in enantiomerically pure forms, which constitute an important class of conformationally constrained peptide building blocks that can be used as dipeptide isosteres in peptidomimetic studies.

Abstract: The present invention provides a chiral furan amino acids, in enantiomerically pure forms, either R or S. The starting materials are being used chiral N-terminal-protected amino aldehydes derived from the corresponding N-terminal-protected protected L- or D-amino acids. The present invention also relates to a process for preparing these chirally substituted furan amino acids constitute an important class of conformationally constrained peptide based molecules that can be used as dipeptide isosteres in peptidomimetic studies.

Abstract: Anticancer peptides which incorporate furanoid sugar amino acids and compositions made using these peptides are described. Methods for synthesis of the peptides and for preparing the furanoid sugar amino acids are disclosed. The peptides and compositions made using the peptides have pharmacological applications of these peptides especially in the treatment and prevention of cancer and tumors.
